FuzzMeasure Pro

FuzzMeasure Pro is an audio and acoustical measurement application you use to perform, analyze, and produce visually stunning graphs of your measurements. Using FuzzMeasure's tools, you can easily gather measurements of a home theater system, recording studio, stage, auditorium, raw loudspeaker components, and more.

FuzzMeasure Pro's design makes a highly complex tool very easy to use. Whether you use FuzzMeasure as a hobbyist, or you work in the acoustics or audio field, you will appreciate the work that went into making it easier to get your work done. Download a copy and try it out for yourself!

Note: Now requires OS X 10.10 or later running on a 64-bit Intel processor.

General

• All-new interface design for OS X Yosemite
• Improved interface when no measurements or graphs have valid content
• Brand-new application, document, and license key icons
• Vastly improved help file
• Autosave and document versioning support
• Document templates to help you get started quickly with a set of commonly-used graphs

Impulse Responses

• Impulse response displays (including the window editor) now show the impulse response with its "negative time data" where it should be

Measurement Records

• Windows may now be set to start (and end) in "negative time" before the impulse response peak
• Calibration records are now accessible (and can now be changed!) in the sidebar
• Level calibration for a measurement record can now be enabled and disabled in the sidebar
• Microphone calibration correction curves can now be enabled and disabled in the sidebar

Image Exports

• You can now export PDF images of graphs
• Exported images can now have their sizes specified
• Raster image exports now allow for an @2x option for exporting retina-capable graphs on the web

Printing

• Individual graphs may be printed by right-clicking on them
• Printing will now include all graphs in the list

Level Meter

• Integrated into the main window
• Now shows dBFS values before being calibrated
• Can display A- and C- weighted values as well (by clicking on the (Z))

AppleScript

• Now allows graph data exports (including comparison, averaged, smoothed, etc.)
• Reverberation Time data can now be exported via AppleScript
• WAV and AIF impulse exports, including bit depth settings

FFT Waterfall Graph

• Can now be viewed in the main window!
• The Waterfall graph can now be automatically aligned to start at the impulse peak
• Improved waterfall performance now allows for higher-resolution waterfall calculations
• Allow settings to use different shaped windows (Hamming, Hanning, etc.) in their calculation
• Waterfall graphs also allow settings for FFT length as well

Energy Decay Curve

• The Energy Decay (Schroeder) curve can now be shown filtered by octave- and third-octave bands

Sidebar/Inspector

• Separate impulse window editor that is accessible from the sidebar

Microphone Calibration

• All-new Microphone Calibration UI
• Microphone calibration records can be attached to input channels in the audio settings
• Automatic online retrieval of calibration data for UMIK-1 microphone owners

Harmonic Distortion Graph

• Now offers configurable harmonic ranges
• Can now display averaged, added, etc comparison data
• Now displays up to the 7th harmonic

Harmonic Distortion Percentage

• Now shown with a logarithmic Y axis
• Now offers configurable harmonic ranges
• Can now display averaged, added, etc comparison data
• Now displays up to the 7th harmonic

ISO 3382 Acoustics Graphs

• Improved bar graphs with support for comparisons
• New line style graphs for the ISO 3382 values allowing improved comparisons

Graphing Interface

• Any of FuzzMeasure's graphs (including the bar and waterfall graphs!) can now be combined with any other
• Multiple copies of the same graph can be shown alongside one another with different settings
• A quick keystroke (command-option-=) now lets you reset graph extents quickly
• Support for pinch zoom and two-finger panning (while holding command+control)
• Each of the graphs carries its own settings that are saved with the document
• Changes to graphs (such as setting extents) are undoable
• Graphs can be dragged around by their title in the graph list to be rearranged

Importing and Exporting

• FuzzMeasure can now import and export WAV format impulses in addition to AIF and TIM files

Graph Calculations

• Many of the graphs are now normalized by default for easier reading
• Mixed sample rate measurements can now be added, averaged, etc. with one another
• All the frequency domain graphs can now be viewed with a linear frequency axis
• Add/Average/Subtract operations for frequency domain graphs have been improved when calculating with decibel data

New Graphs

• Clarity (C30, C50, C80) graphs are now available
• The Definition (D50) graph is now available
• The Early Decay Time (EDT) graph is now separate from the Reverberation Time graph
• Low Frequency Waterfall graphs with a linear frequency axis over the 20-200Hz range

Measuring

• Clipping is now detected during measurements (on both the measurement and correction channels)
• The correction channel is now also checked for an adequate level during measurement
• Audio settings will now enforce a shared sample rate among mixed device environments
